Sandtrix - Tetris With Falling Sand Physics

Sandtrix reimagines Tetris by replacing rigid blocks with piles of colored sand. Pieces still fall in familiar shapes, but when they land, they dissolve into individual grains that pour, pile, and flow like real sand. Clear lines by connecting same-color sand across the grid — the physics make every placement unpredictable and mesmerizing to watch.

How to Play Sandtrix

• Move pieces: Arrow keys to shift and rotate falling tetrominoes
• Watch them crumble: On landing, blocks break into sand grains with physics
• Connect colors: Link same-color sand horizontally to clear lines
• Manage the pile: Sand slopes and avalanches — gaps fill differently than classic Tetris
• Survive: Game ends when sand stacks above the danger line

Sandtrix FAQ

How is Sandtrix different from Tetris?

Blocks become flowing sand particles. Clears require color connections, not full solid rows.

Can sand block my next piece?

Yes. Avalanches reshape the pile — plan for sand sliding into unexpected places.

Is Sandtrix relaxing or stressful?

Both. The physics are calming to watch, but the stacking pressure ramps up like classic Tetris.
